my baby 3.5 month old baby she sleep in night very well but in day time she not sleep very well 30/45 min sleep then she wake up in a whole day .. why this happen when she wake up then she play not crying her sleep time very less

A. A minimum should be at least 8 to 10 hours in a day for a child is maintaining that sleep then there is no problem and during the daytime try to maintain proper silence by putting earplugs or coordinate so that your child doesn’t get disturbed outside disturbance and noise this is going to help
